Specification of Letters Patent.

Application filed October 14.1504, serial No. 228.417.

To aZ whom it may concern,.-

Beit known that I, JOHN M. LANsDEN, Jr., a citizen of the United States, residing in Orange, county of Essex, State of New Jersey, have invented4 certain new and useful Improvements in Vehicle-Wheels, of which the following is a speciiication.

The object I have in view is to produce a wheel suitable for vehicles, but particularly automobiles, whereby the friction will be reduced, lubrication will be effected, dust excluded, and the end capretained securely in place. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a sectional view of a hub taken on the line 1 1 of Fig. 2. Fig. 2 is a View, partly in section, taken on the lines 2 2 of Fig. 1. Fig. 3 is an end view ofthe outer portion of the hub, showing the cap in section. Fig. 4 is a plan view of the same. Fig. 5 is a sectional View taken on the lines 5 5 of Fig. 1. In all of the views like parts are designated by the same numerals of reference.

Incarying out my invention I provide a hub 1, having a cylindrical bearing-surface 2 and a flange 3. Surrounding the hub is a flanged collar 4, and between this collar and the iian e 3 are secured the s okes 5 by means o bolts 6. Between the earing-surface 2 and the spindle 7 is a bushing or sleeve 8. This bushing 8 is free to rotate upon the spindle 7 and within the hub 1.' The inner surface of the bushing is provided with two or more longitudinal spiral oil-passages 9, and its outer surface is provided with similar passages 10. The passages on the inside of the bushing are arranged inthe opposite direction Jfrom those in the outside-that is to say, if the passage 9 is a right-hand passage then the assage 1() on the outside will be aletthand) one, causing the passages to be of opposite twist.

A ring 11 of fiber is arranged on the inner end of the hub and bears against a shoulder 12, formed thereon. Enga ing with the ring 11 is a second ring 13 ol? against the inclined portion 14 of the axleshoulder 15.l The ring 13 is' of less depth than the ring 11. ring 16, oi felt or similar material. These rings constitute a dust-excluding device.

The outer extremity of the spindle 7 is reduced, forming a shoulder 17. The reduced portion is threaded at 18 for the reception of an end cap 19, the said cap being screwed ber, which bears Outside of the ring 13 1s a` thereto. The cap 19 is provided with a cir- Patentea July 3, 1906. c

cular faceportion20, which bears a ainst the hub 2 and a shoulder portion 21, a the shoulder 17 at the spindle. Between these two portions is awasher 22, of any suitable material'. Theend cap-19 is prevented from accidentally turningby means of a cotter 23. The end cap is adjustedv until it pinches the washer 22. The circular face portion 20 will then engage with the hub and force the latter inward. This will compress the washers 11 and 13,- and the latter engaging with the 'curved portion 14 of the enlargement 15 on the axle will be expanded, compressing the felt washer 16 between it andthe hub, thereby producing an elicient dust-excludirlg dlevice and a means for preventing escape o o1 ring 16 `can be determined by the thickness of the washer 22, a greater or lesser thickness of jacent to the latter being employed, as'required.- The cap 19 is rovided with wings 24, which with the barrelpand iiange of the cap constitute oilchambers 25. An oil-passage 26 in each charnber serves as a means of communication between the space between the axle and the hub and the outside of the cap.

A cylindrical dust-cap v27, having a hexagf onal portion 28 for attachment of a wrench and a threaded portion 29, en ages with threads 30, formed upon the hui 1. This dust-cap forms anloil-tight joint by means of these threads and also serves as a reservoir for lubricant. The inner edge lof the cap is provided with a series of notches 31, which engage with one extremity of a spring y32,

the other extremity of the latter engaging with a notch 33, formed upon the'iiange 4.

The spring is formed of wirejof square or rec-- tangular cross-section, so that it will not roll. The convolutions of the spring turn in the opposite direction from the threads 30-that is to 's ay, if'the threads 30 are right-handed threads the spring must be a left-handed one.

In order to get the best results from the bearing-surfaces, the spindle, hub, and bushing should be of different material -and the thickness 'of the bushing shouldI bear a definite relation to the' frictional character of the materials. If, as an instance, as I'have found in practice, the hub be made of malleable iron and the spindle oi steel, the bushing made of bronze and softer than thes indie or hub, and the halfydiameter ofthe spindle being seven-eighths of' an inch and the half-diameter oi the central bore of the hub being roo one and one-eighth inches, leaving the sepa-i rating-space one-fourthv of an inch and the 4bushin of sufficient thickness to make a close fit, an the parts being properly lubricated', the surfaces between the hub and bushing ,and Abetween the bushing and the s indle will each have the same frictional c aracteristics-that is to say, the friction will be transferred to both 'surfaces in about e ual amounts and the bushin will rotate at ess.

speed than the hub. T 's will Vreatly reduce the friction'and will double t e oil area. The hub being rotated will supply oil vby means of the cover 27 to the uppermost oilchamber 25, allowing oil to pass through the passage 26 into the space between the spindle and the hub. The bushing being in constant rotation with the wheel, the oil will be moved through one ofthe spiral passages 9 or 10 into the bushing in one direction andreturn in the other direction, passing out through the lowermost oil-passage 26 into the dust-ca 27. It is to be noted that the bushing is ee to move longitudinally upon the spindle to a limited extent; but it cannot pass beyond the confines of the cap .19 and 'the ring 11, By coiling the spring 32 in the opposite direction from the threads 30 an efiioient lock for the cap 27 will be produced, as the lock cannot be unscrewed without compressing the spring. In order to remove the cap, one extremity of the springis disengaged from the notch by the insertion of a suitable tool. This form of look avoids the necessityof making an opening in the cap, as has heretofore been the case, and provides something that is neat and inconspicuous and which will not readily get out of order.

The specific oiling devi e disclosed herein is not claimed in thisy app ication, but forms the subject-matter of a divisionalapplication I 4filed by me on the 23d day of June, 1905, Se-

rial No. 266 ,545.

1. In a vehicle-wheel, the' combination with a spindle having ashoulder thereon, of a hub having a shoulder, fiber rings between the shoulders and a ring of softer material between the shoulders, and means for compressing the fiber rin s between the shoulders, and for expanding t e softer ring. 2. In avehicle-wheel, the combination with a spindle, of ya hub surrounding the same, a flaring shoulder on the spindle, a shoulder on the hub, a washer 'bearing against the hubshoulder, a Washer bearing against the flaring shoulder and the first washer, and means for expandingthe second washer.

3. In a vehicle-wheel, the combination with a spindle, of a hub surrounding the same, a flaring shoulder on the spindle, a shoulder on the hub, agwasher bearing against the hub-` shoulder, a washer earing against the flaring shoulder and the first washer, and of less diameter than the first washer, and arin of soft material surrounding the second was er, and means for expanding the second washer.

4. In a vehiclefwheel, the combination with a spindle,
